Sand Snakes is a term used to refer collectively to the bastard daughters of Prince Oberyn Martell.[1] The name references the Dornish bastard surname, Sand, and their father's nickname, “the Red Viper”.

Prince Oberyn's eight daughters have been born to five different mothers,[2] and while they differ in appearance from one another, they are said to all have their father's eyes.[1]
